2011-2015 All models (except Routan)- AC Compressor
Replacement, Refrigerant Circuit Flushing Requirement

When replacing the Air Conditioning compressor it is necessary to flush the entire system to remove all the
PAG oil. Replacement AC compressors come with a full charge of oil. Any time another compressor is
installed with a different vendor (Sanden to Denso) it is necessary to replace all the oil in the system to the
new vendor type PAG oil.
Note:
AC Compressors come with a full oil charge, after flushing the refrigerant circuit no oil needs to be
added during recharging. Always verify the oil amount in the new AC compressor.
